The center cell is stripped out of the packjob so fast that it is pulling lines from the tailpocket, leading to a linedump and a very hard opening.
Pilotchute was a 36″ AV ZP, which I would say is a reasonable choice for a tracking jump, opening at approximately 2500m ASL with a 280 sqft canopy. It was a pretty fast track, indirect control was in place (rubber band around the fold two times).
I don’t really have anything wiseass to say to this issue, I jumped few seconds before with the exact same setup… Thanks to the jumper for letting me use his footage.
Maybe just the obvious, a too big PC for the delay can lead to all kinds of problems, out of stage deployments, center cell stripping, hard openings, damaged equipment, and other fun stuff.
